Anatomical terminology []

The external spermatic fascia (intercrural or intercolumnar fascia) is a thin membrane, prolonged downward around the surface of the spermatic cord and testis. It is separated from the dartos tunic by loose areolar tissue. It is occasionally referred to as 'Le Fascia de Webster' after an anatomist who once described it.

It is derived from the aponeurosis of the abdominal external oblique muscle.
